FILLrNe-REPLENISHING LooM. i

i Application filed August 2, 1928. Serial 1V\To.;297,007.

This invention relates to filling replenishing looms wherein the filling in the shuttle is changed from time to time, and is more parl ticularly' directed to the means for holding the filling carriers in the filling feeder or magazine.

It is now the ordinary practice to provide filling replenishing looms with a rotary filling feeder or magazine for the support of the loaded filling carriers which are to be transferred to the shuttle, and such filling feeders or magazines have usually been provided with means for holding the heads and tips ofthe filling carriers while in the hopper and yet permit the filling carriers to be transferred from the hopper to the shuttle.

TWhere the filling carriers are of the cop skewer type, thetip end portion of the cop skewer is liable to be burred orV roughened when the cop skewers are placed in the feeder or magazine,` and likewise when they are transferred tothe shuttle, and since the filling is withdrawn from the cop skewer lengthwise thereof, this burred or roughened end portion is liable to chafe or injure the filling during weaving, and inv some cases cause breakage thereof. It is not expedient, therefore, to support filling carriers of this type in the filling feeder or magazine in accordance with the usual methods, and the object and purposes of the present invention are to provide a tip support for fill-ing carriers, especially of the cop skewer type, which will be eRective in maintaining the cop skewers in proper position in the feeder or magazine and at the Y same time avoid any injury tothe end of the filling carrier, either while it is being placed in the hopper or transferred therefrom.

ln accordance with thepresent invention, the tip holding disk of the rotary hopper is provided with seats which engage the filling carrier near its tip end portion and serve to position the filling carrier for transfer, while in connection therewith there are trip engaging members having slots longitudinally thereof through which the pointed end of the tip of the filling carrier-may extend so that it will not be injured. Cooperating with theA seats of the tip holding disk and the tip engaging members are a' series of lretainers wiiich serve to maintain or hold the tip portions of the filling carriers in the seats of the eXit of the filling carriers, withoutinjury to the tip portions thereof.

it is desirable in most cases to insure that filling carriers shall not rotate` on theirlongitudinal axes while in the hopper, and to this end the present invention provides a simple but effective expedient of a slabbed-off portion of the filling carrier or skewer atthe tip thereof,.which in cooperation with the walls of the tip seats in the disk serve thedesired purpose. f 5

rlhe invention and new combination of parts and novel features thereof will best be made clear from the following description and the accompanying drawings of one; good Fig. 2 is an enlarged detail view of a-section oFf th tip holding disk looking from the right, lg- S Y Fig. 3 is a section on the line 3-3 of Fig. 2; Fig. 4 shows a portion of the tip holding disk and the features of the invention associated therewith-g Y I l Fig. is a sideview of a cop skewer which may constitute the type of thefilling ycarrier employed in the filling and l.

Fig. 6 is a detail showing the slabbed-OH end portion of the cop skeweror'fillingv carrier. r 'i The rotaryI Ifilling feeder or magazine comprises the head -disk l and the tip `holding disk 2 which,-invtheir-associated relation, are mounted for rotary movement upon ay stand 3 which may be conveniently supported upon the loom frame at-thefilling replenishing side thereof. v The transferring mechanism by which theifilling carriers are transferred from the filling feeder'or magazine to the shuttle from time'to time may'beof any usual. construction and as herein shown comprises the transferrer 4 mounted upon av stud 5 supported from the hub portionl 6 of the stand, but since "the details of the transferring mechanism 'and actuating means therefor form no partof the present invention and are now well understoodin the art, V further illustration and description thereof is unnecessary. v

feeder 'or magazine;

l 'The head disk 1 is, as usual, provided with supports 7 for the head portions 8 `of the filling carriers and these may be of wellknown. construction. i

Th'eti'p holding disk 9is mounted for rotary movement with the hea-d disk 1, as usual,

and. its outer peripheral. portion is provided with a flange 1l) extending axially of the feeder or magazine. The tip holding disk 9 has a series of openings 11 which terminate at their lower portions in seats 12 for the tip end of the filling'ca-rriers, andv in order that the filling carriers or cop skewers may be` readily placed inE engagement' with the seats 12, the openings-11 are enlarged at the lupperlportion,.as indicated in Fig. 4, and the si-de walls 13L andl 141 thereof converge downwardlys' and. form.` at their lower unioni-the rseats 12: for! the filling carriers, the construction being'such that the-l filling carriers may be conveniently'assembledwith theirtip portions in'.engagement.with` the seats 12 in the tip holding' disk.

Mounted upon the tip holding disk 9 at the-outer side thereof are a series of tip enggagin'g niembersr 15 whch1 may be secured to they tip: holding' diskrby: suitable means, such as the; bolts l'pand each. of the tip.' engaging members lis yieldable or resilient.l The tip engaging members 15 have their upper end portions flaring, as at 1.7and'l are each o provided-,wth av slot; 18 which extends longitudinally of the tip engaging members. Since; it is desirableftliat the extreme point or tipiof. the filling carriers or skewers shall not be injured as they are placed in the feeder or magazine and when they are transferred therefrom, the slot-s 1:8 are carried upwardly into. the flaring portion of the tipengaging members, and through suchslo'ts the tip end portions of the lilling carriers 19 project, as indicated ati20,.Fig. 3.

'llhe slots- 18 of the* tip engagingA members 'are of less width than the diameter of the filling carriers or copi skewers, so that the copskewers themselves,- while having. their pointedtip ends 20 extending throughthe slots, .arelnevertheless, under longitudinal stress, by reason of the engagement of the walls-fof the slots 18-with the tapering tip endAV portion of the skewers onlillingcarriers.

Associated with the tip holding'disk 9 are a series of tipretainers121 whichmay be suitably secured to.V the tip' holding disk,y prefere ably betweenV the disk` and: the tip engaging members-.15. The? tip retainers 21 serve to heldg or Ymaintain the tips ofthe filling carriersfor skewers in theseats of the disk and to this end theupper portions of the retainf ers are reversely formed to provide a portion `22.whichl acts vlaterally of theffilling carriers andoverl-ies the tip portions thereof between the, tip engaging` members 15 and t-hetip holding,Y disk. The, extreme upper portion. ofthe retainers 21 is reversely turned, as at skewer 1.9v is slabb'ed-olf, as at24,

nraaaie then'be forced". downwardly Vpastthe associatvedy retainer 21* into' it's seat" 1:2 in` the disk,

without dangerl of causing a: burred' or -roughenedsurface to be formed on thepoint'-Y Ved end ofth'elilling carrierorcop skewer.

Similarly, during transfer, thefillingcarrier ror cop: skewer` may be" transferred from the hopper totheshuttrle-without danger of burring or roughening the* pointed tipend: of the fillingcarrier or skewer:

` In order that the-cop skewer or'filling car"- rier mayaet upon the associated retainer 21 to deflect it laterally as thel cop skewer is seated, oneof the walls, as 113,` of" theopening l1, is projected laterally, with the result that it will cause the-cop skewer to bear upon the upwardly ila-ring portion 235 of the retainer and move it laterallyV until, when the ti'p of the? skewer or filling carrierjh'as passedithe retainer, the latter will move back' to' its original position and thereafter maintain" the cop skewer or'lilling carrier in'itsseat 12' of the disk. Y

Inasmucllrasv one of thefunctions'of the tip engaging-members listo act with stress longltfiidinally of vt'hefilling carriers or cop skewers, the-slots 118in-tlie tip `engagin'g'mem'`- bers are so pro ortifonedi with'respect to the diameter' of t efilling carrier or cop skewerthat the extremefortip end ofthe fill ingfcarrier or cop-skewer may project through the slot' and'tlie wallsofthe slot thereafter engage thel substantially conical end of the filling carrieror sl'rewer/ andl impart longitudinalistressrthereto. l

As hereinbefore mentioned', it isi desirable thatthe cop skewers or filling carriersl shall not turn. about their longitudinal axes when in the hopper, and as indicatedl Figs. land 6, the tip portion ofy the fillingfcarrier or copwithfthe result that when the cop skewerv or filling carrier has been moved downwardly in the'slot' 11 into engagement withV its seat' 12,'the wall ofthe seat which embraces the cop skewer or.l

filling carrierwi-llv engage the sl'abbed-off portion 2.4L and thereafter prevent any rotary' movement ofthe filling carrier or cop-'skewer in the hopper. Y
